Spectral scaling in the turbulent Earth's plasma sheet revisited
Nakamura, R.; Lucek, E. A.; Baumjohann, W. +6 more
Bursty bulk flow associated magnetic fluctuations exhibit at least three spectral scaling ranges in the Earth's plasma sheet. Two of the three scaling ranges can be associated with multi-scale magnetohydrodynamic turbulence between the spatial scales from ~100 km to several RE (RE is the Earth's radius). These scales include …
Observations of linear and nonlinear processes in the foreshock wave evolution
Fränz, M.; Glassmeier, K. -H.; Narita, Y. +2 more
Waves in the foreshock region are studied on the basis of a hypothesis that the linear process first excites the waves and further wave-wave nonlinearities distribute scatter the energy of the primary waves into a number of daughter waves. To examine this wave evolution scenario, the dispersion relations, the wave number spectra of the magnetic fi…
Multi-point observations of intermittency in the cusp regions
Lamy, H.; Chang, T.; Echim, M. M.
In this paper we investigate the statistical properties of magnetic field fluctuations measured by the four Cluster spacecraft in the cusp and close to the interface with the magnetospheric lobes, magnetopause and magnetosheath. At lower altitudes along the outbound orbit of 26 February 2001, the magnetic field fluctuations recorded by all four sp…
Phase space holes and elementary radiation events
Pickett, J.; Pottelette, R.
Using high-time resolution measurements from the FAST and CLUSTER spacecraft we analyze different types of fine frequency structures of Auroral Kilometric Radiation (AKR). Based on the results from previous numerical simulations, we emphasize that the recorded frequency structures are the ones which are expected to occur on the low- and high-poten…
